Title: Steel sheet having hot dip aluminized coating excellent in workability, heat resistance and oxidation resistance and its producing method
Inventor: HOSOMI KAZUAKI
IPC: C23C2/40
Filed: 2000-02-22
Abstract: PROBLEM TO BE SOLVED: To produce a steel sheet having hot dip aluminized coating, which suppresses the development of a hard and brittle Fe-Al-Si alloy layer and is excellent in workability, heat resistance and oxidation resistance. SOLUTION: This steel sheet having hot dip aluminized coating has the hot dip aluminized layer 1 through an Fe-Al-Si-Mo alloy layer 4 on a substrate steel 2. In the interface between the substrate steel 2 and the Fe-Al-Si-Mo alloy layer 4, an Fe-Mo alloy layer 5 may be arranged. The steel sheet is produced by dipping a hot dip coated original steel sheet into a hot dip aluminizing bath containing Si after applying an Fe-Mo pre-coating on the one side surface or both surfaces of the hot dip coating original sheet. Thus, the Fe-Al-Si-Mo alloy layer 4 and the Fe-Mo alloy layer 5 function as a barrier, and thus, the alloying reaction of Fe-Al is suppressed.
